  • WELDING STATE DETERMINATION DEVICE, WELDING STATE DETERMINATION METHOD, AND PROGRAM
    Publication number: 20190358726
    Abstract: Provided is a welding state determination device that can easily determine the welding state. The welding state determination device includes: an acquisition unit that acquires a pulse waveform of a pulse current or a pulse voltage supplied to an electrode for pulse arc welding, the pulse waveform including a falling portion, a rising portion, and a flat portion therebetween; a preprocessing unit that shapes the pulse waveform such that the flat portion has a predetermined width; and a determination unit that determines a state of the pulse arc welding based on a difference between the shaped pulse waveform and a normal pattern created based on a plurality of past shaped pulse waveforms.
